"Have you never entered the otherworld before?" Yefan glanced at the warriors behind him and asked.
"N-no, we haven't," Commander Zhao responded.
As soon as they entered, he could immediately feel the difference in gravity compared to Earth.
Just standing there made breathing more difficult, and his internal organs felt uncomfortable as well.
"You'll get used to it over time," Yefan said calmly.
"The gravity here is different from Earth."
At that moment, they noticed a large number of figures rushing toward them from the front.
"Aliens!?"
Everyone had sharp vision, and they quickly made out the silhouettes of these beings.
A large group of aliens was charging toward them. In an instant, Yefan swung his long sword.
Countless powerful sword energies burst forth at that moment.
Whoosh, whoosh, whoosh—
The sound of air being sliced echoed through the sky!
The aliens that were rushing forward were immediately sliced in half by the terrifying sword energy.
These aliens appeared large and robust, but Yefan easily cut them down with a single strike.
In a short amount of time, all the charging aliens were severed in two.
None of them could even get close.
Commander Zhao could feel himself slowly adapting to the gravity.
"So powerful…"
He watched in awe as Yefan stood at the front, casually swinging his sword. The devastating sword energy tore through the air and struck the enemies ahead.
Many aliens were split in half instantly.
The others watching were also taken aback.
They had struggled to penetrate the aliens' tough bodies with bullets before, yet Yefan could cleave them in two with ease.
As more and more aliens fell, those further back hesitated and stopped charging forward. Fear was evident on their faces, seeing so many of their comrades killed before even reaching the enemy.
Eventually, the aliens fled in all directions.
"Let's move on. Next time aliens or beasts appear, it'll be your turn to fight," Yefan said as he walked ahead.
The group nodded in agreement.
Due to the different gravity, even the vehicles they had brought struggled to move.
"The energy in the air is so dense," one of the soldiers commented, taking a deep breath and realizing how rich the energy around them was.
Training in such a high-energy environment would undoubtedly speed up their progress.
"This is indeed a good place to train," Yefan smiled.
"But it's also very dangerous."
As soon as Yefan finished speaking, the ground around them began to tremble slightly.
What's that!?
Feeling the vibrations, Commander Zhao and the others widened their eyes.
What is happening?!
The group instinctively tightened their grip on their swords as they noticed the ground bulging upwards in several places.
Large, lizard-like creatures emerged from the earth, massive in size.
"It's your turn," Yefan said calmly.
"Kill!"
With a shout, the warriors gritted their teeth and charged forward with their weapons.
Hiss, hiss, hiss—
The lizard-like beasts let out strange hissing noises as they launched their own attacks on the warriors.
In an instant, the soldiers clashed with the beasts in fierce combat.
Suspended in the air, Yefan watched their battle.
Only through real combat could they sharpen themselves.
Unless there were mortal injuries, Yefan had no intention of stepping in to help.
The group stayed in the otherworld for a full week!
After a week of constant training, every warrior had become visibly stronger.
Their bodies had grown more muscular, and their skin had become tougher.
The abundant energy in the otherworld had also accelerated their cultivation.
Most of them had already reached the Third Rank Warrior level.
They hunted the beasts, then ate their meat, which provided a great deal of energy.
"Look, that entire area is covered in Yuan Refining Grass," Yefan said, leading the group to a large patch of lush green grass in the distance.
This grass resembled an oversized version of Earth's grass.
"Yuan Refining Grass is a key ingredient for refining Body Tempering Pills," Yefan explained.
"After taking the Body Tempering Pill, your body tempering will become much more efficient."
Yefan's knowledge of various cultivation techniques and pill-refining methods came from the memories of previous sword masters.
His mind was like a vast library of ancient texts, filled with countless methods.
After searching through his mental archive, he quickly recalled the method for creating Body Tempering Pills.
"There's so much of it. Are we taking it all back?" Commander Zhao asked Yefan.
"Yes," Yefan replied, gripping his Yefan Sword and raising it high.
Slash!
With a single sword strike, countless sword energies shot forward, slicing through the Yuan Refining Grass.
With a thought, Yefan summoned his Spatial Cube, and in an instant, the vast quantities of Yuan Refining Grass were absorbed into the cube.
This trip to the otherworld had not only yielded Huìyuán Grass and Yuan Refining Grass but also led them to discover a mineral vein.
They had mined a large amount of ore, all stored in the Spatial Cube.
"That's enough. Let's head back," Yefan said.
Leading the warriors, he retraced his steps back to the spatial rift.
Soon, they crossed through the rift and returned to Earth.
As soon as they emerged, they immediately felt the change in gravity.
"It feels like I'm floating!" Commander Zhao said with excitement, jumping slightly to test the difference.
The others also noticed the change, finding that they could run and move much faster than before.
"Some of you will stay here, while others will return. Lead new warriors into the otherworld for training," Yefan instructed.
"Understood!"
Following Yefan's orders, a group stayed behind while another group, led by Commander Zhao, returned to Tianyun City.
